Is this green building?

What do you understand by “green building”?

5

A green building is the one that uses less water, optimizes energy efficiency, conserves natural resources, generates less waste and provide healthier space for occupants as compared to a conventional building. We would like to show some awesome constructions that are ancient and available today which are naturally ventilated…

The concept of green building can be traced to the energy crisis and environmental pollution concerns of 1960s to 1970s. There are numbers of motives for building green including environmental and economic benefit. To bring together a vast array of practices techniques and skills to reduce and ultimately eliminate the impacts on environment and humans. To emphasis on taking advantage of renewable resources.

GOALS

9

It enhances and protects eco system. It improve air and water quality. It reduces waste streams. Conserves and restores natural resources. It operating cost is very less It improves quality of life. It improves occupant productivity. Enhances asset value and profit. It optimizes life cycle economic performance. It enhances occupants health and comfort. It minimizes strain on local area .

IMPORTANCE OF GREEN BUILDING

10

India ranks 3 among top 10 for LEED green buildings with 1883 certified projects. With Canada being on the first place with 4814 projects. China being second with 2022 projects. And US with 53908 projects but is not considered in ranking.

Overall standing

11

In India 1). LEED(Leadership in Energy & Environmental Design) by IGBC (Indian Green Building Council). 2). GRIHA (Green Rating for Integrated Habitat Assessment) by TERI (The Energy Research Institute).In UK: Breeam Building Establishment Environmental Assessment Method.In japan: Casbee Comprehensive Assessment system for building environmental efficiency.

RATING SYSTEM

12

LEED RATING SYSTEM

RATINGS CREDITS REQUIREDLEED Certified 23-27LEED Silver 28-33LEED Gold 34-44LEED Platinum 45-61

This rating system encompasses five environmental categories :1. Sustainable sites 2. Water efficiency3. Energy efficiency4. Material efficiency5. Indoor environmental qualities.This system gives 61 credits.

13

GRIHA assesses a building out of 34 criteria and awards points on a scale of 100. In order to qualify for GRIHA certification ,a project must achieve at least 50 points. Projects scoring….o 1.50-60 points is certified as 1 star GRIHA rated building.o 2.61-70 is a 2 star GRIHA rated building.o 3.71-80 is a 3 star GRIHA rated building.o 4.81-90 is a 4 star GRIHA rated building.o 5.91-100 is a 5 star GRIHA rated building.

GRIHA RATING SYSTEM

Passive architecture should be adopted to minimize negative impacts on environment. This contains 2 options . o (a). Climate responsive concepts and design features E.g. : orientation, skylights, shaded courtyard, shading from trees etc.o (b). Passive cooling/heating technologies E.g. : wind tower, earth tunnel, geothermal technologies

SUSTAINABLE ARCHITECTURE & DESIGN

15

Erosion of soil should be controlled Fertile topsoil should be stockpiled prior to construction , for future reuse or donation. Provision for basic amenities so as to reduce negative impact caused from auto mobile use. Minimum disturbance to the nearby topography or vegetation Restoration of disturbed site area by design vegetated spaces over built up structure and on the ground, for at leas 30%of the site area.

SITE SELECTION & PLANING

16

Reduction in embodied energy & operating energy. High performance building reduces about 30% of the energy consumption Studies show that wood has low embodied energy as compared to that of steel and concrete. Use of high windows and insulation in walls, ceiling and floors to reduce operating energy. Placing of awnings, porches and trees to shade windows during summer and maximize solar gain in winter.

ENERGY EFFICIENCY

17

Efficient heating and cooling systems. Building automation system.Energy efficient commercial lighting, such as leds, are used to reduce energy.Reduction of amount of energy lost through heat from out dated lighting system.Automation system are the main sources of energy efficiency in existing buildings.Based on occupancy, outside temperature, light and time of day automation system can reduce energy usage by activating heating, cooling or led lighting only in those area of building where they are necessary.

ENERGY EFFICIENCY

18

Reducing water consumption and protecting water quality are key objectives of any sustainable building. Critical issues of water consumptions is that its demand in the particular area exceeds its replenishing ability. By designing a dual plumbing that recycles water in toilet flushing or by using water for washing the cars Waste water may be minimized by utilizing water conserving fixtures such as ultra low flush toilets and low flow shower heads. Bidets help eliminate the use of toilet paper , reducing sewer traffic and increasing possibility of re-using water on site.

WATER EFFICIENCY

19

Limit the use of turf on the site, instead plant a native species of the particular area. Treat waste water generated from site , so as to avoid polluting the receiving streams by safe disposal. Enhance ground water table usage thus decrease municipal water demand through effective rainwater management.

WATER EFFICIENCY

20

Green building emphasise waste reduction. Construction wastes & demolition debris are the main wastes produced during construction process & these wastes degrade the quality of environment. Green building ensures waste reduction by:1. Reuse & minimisation of construction wastes & debris & diverting them to recycling units.2. The increased use of recycled contents & waste by-products in construction materials.3. The use of existing building structure & reclaimed building materials in the core & shell of project.4. Designing the structure to produce less scrap & execute it according to the plan

Waste reduction & Material Efficiency

21

Green Buildings reduce construction wastes by 50% compared with that of similar conventional buildings. For green building, building materials such as lumbers from forest, recycled stone, recycled metal and any other industrial recycled goods which are non toxic like coals, sand etc are used.

Waste reduction & Material Efficiency

22

This one of the five category in LEED standards that concerns with the comforts and well being and productivity of occupants. Provide adequate air ventilation, so as to avoid pollutants affecting indoor air quality.

The previous building was constructed 90 years back. Exhibits bunglow type with open space surrounding it. It served 75 years and since then it was lying unused. It was deteriorated since last 10 years. This building was used by East India Company officers before independence & then it along with the other buildings and spaces were given to establish university in 1949 by His Highness Maharaja of Baroda state. The building due to lack of maintenance and repair got deteriorated and finally was abandoned after .

1.CII-Sohrabji Godrej Green Business Centre, Hyderabad.

This building is one of the worlds best example of passive architectural design . At the time of inauguration it was the first building outside US to be awarded LEED platinum rating. The GBC is unofficially worlds most environmental friendly construction for the use of water and energy efficient technologies. This building is literally made out of recycled material.

GREEN BUILDINGS IN INDIA

This building does not discharge any waste water and recycles all the used water. The building compromises of two air conditioning towers where incoming air is cooled up to 7 to 8 degree by spraying water there by reducing the load of air conditioning energy consumption. The roof is covered by gardens as well as solar photovoltaic thereby reducing the energy consumption by 60%against a comparable conventional building.

3.Infosys Limited Mysore building.

The overall water consumption of this building is 58% less as compared to other building of same capacity. Most of the waste water is recycled and used for irrigation purpose. The buildings design comprises of an efficient building envelope, which includes insulated walls and roof, along with spectrally selective double glazed windows which are appropriately shaded More over, efficient equipment and smart automation is used across the building that leads to a 40% reduction in energy cost. Almost 90% of the work spaces inside the building includes light shelves that ensures that natural light travels as deep as possible inside the building.
